    I agree the tangent is the proper and concise way to do it.
    But it's not what the examiners want for this Bio spec exam and I don't know why. When you look at past papers / specimen paper, it doesn't say what they did to work it out but when you look at what method marks and calculations they have done along with the general correct answer, it is obvious that they have drew across rather than a tangent.
    Right not going to lie first I drew lines then read question is said I remeber 'show on Diagram how you got your answer' trust me that means tangent 😂😭😂 so I did the beautiful tangent

    as always i made a couple of silly mistakes and gave away a few very easy marks but i still found that paper ok

    i hated that graph question, did anyone get their rates between 1.2x10^-3 and 4x10^-3,
    yh it was standard form so you can convert to decimals later if you want

    dont stress about that, its wrong imo and everyone will lose all those marks so wont really affect anything at the end of the day

    How did people find it? I've been hearing a range from 'pretty easy' to 'difficult'

    I found it difficult tbh. Hopefully the next paper will be ok

    How many marks do think you have all dropped ?
    Don't know how many marks I'll lose for not writing in standard form, didn't mention ATP synthase (mentioned condensation, ADP + Pi and "enzyme"), last question question 9 probably a few marks here and there, lol yeah. And maybe marks everywhere in the paper because loss of keywords and all that but not too bad I think.

    I reckon low-ish grade boundaries for this paper. 70% A? 75%?

    for the microscope question, said something along the lines of what feature of the microscpe can be seen from the image, what did u guys write, i wrote the image being black and white

    No it can't be black and white because how can u differentiate form TEM, it was 3D

    Wasn't it about Scanning Electron Microscopes?
    I wrote 3D image.

    It was because the resolution was high as objects close together was distinguishable such as the matrix

    That would be for both SEM and TEM as they are both electron microscopes. They specifically asked for SEM.

    That's what I thought! What did u put in your ans? I said SEM has lower resolution than TEM harder to distinguish two points(maybe this is a load of sh*t)😂😂
